The DAC in DV2 is outstanding. I got my DA2 paired with Aurender N10 and couldn’t be any happier.
If you plan to keep DV2 then ask your dealer to loan you NS1...this pairing will have one distinct advantage that no other streamer will offer. The NS1 is equipped with EMM’s proprietary EMM Optilink interface which will allow NS1 to be galvanically isolated from EMM D/A Converters. Along with EMM’s Optilink, EMM D/A Converters like the one in DV2 can receive media and track information on their display via RS232 connection.
I did not care to pursue this option cause I am very content with N10’s superlative sound and it’s excellent proprietary Conductor iOS app.
